With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.

Designed for macOS Big Sur.

Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.

Document tabs.

The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.

Navigator font sizes.

The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.

Code completion streamlined.

A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.

Redesigned organizer.

An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.

SwiftUI

SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.

Universal app ready.

Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.

Updated automatically

When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.

Test multiple architectures.

On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.

Multiplatform template

New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.

Improved auto-indentation

Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.

StoreKit testing

New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.

Get started.

Download Xcode 12 and use these resources to build apps for all Apple platforms.

Welcome to the FreePascal on the Macintosh page. Here is information especially for you who want to write a program for the Macintosh.

News:

2009-02-09:

The download statistics indicate that the snapshots below are still downloaded a lot. Note that all fixes from those snapshots are also in the official release of FPC 2.2.2 (and will be also in later versions, when they become available), which was released in August 2008. Since FPC 2.2.2 also contains many additional fixes, we recommend you to use that version. It is available from the regular download pages.

2007-11-14:

There are some errors in the new linker shipped with Xcode 3.0/Mac OS X 10.5. A detailed overview was posted to the fpc-pascal mailing list. We have worked around most of those issues and created (stable) development snapshots for both PowerPC and Intel. These are intended to be installed on top of the 2.2.0 release version. Future releases will have these fixes incorporated.

One linker bug cannot be completely worked around in the compiler, which is related to the Stabs debugging format. For this reason, we recommend to switch to the Dwarf debugging format on Mac OS X 10.5. On the command line, you can do this by using -gw instead of -g to generate debugging information. In the Xcode projects, add -gw at the end of the FPC_SPECIFIC_OPTIONS project setting for the Debug configuration.

2006-08-27:
Regular snapshots of FPC 2.1.1 (both for PowerPC and for Intel - the latterdenoted as i386) are now generated by and available from the Lazarus team.
If you only need the compiler (to either use it from the command line or from Xcode),you only have to download and install the 'fpc' package.
2005-12-18:
Version 2.0.2 that was released a few weeks ago has all fixes and improvements of the 2.1.1 snapshot that was here (like Mac Pascal style objects and creationof dynamic libraries). Additionally, it doesn't suffer from the installationproblems the 2.1.1 snapshot installer had. Get the release here.
2005-07-23:
The 2.1.1 snapshot that was here is no longer available.
If you really need to be up to date with FPC,please consider using Subversion, and build the compiler by your self.
Some changes:

• No more '_main' symbol in the system unit (so can link with C main programs)
• Shared library creation support under Mac OS X
• Several bugfixes related to overflow checking on PPC

2005-06-29:
There is now a wiki page covering porting issues, from traditional mac pascals to FPC.
2005-06-21:
A FPC 2.1.1 snapshot is available here (10.8 MB, does not include the PDF documentation). It includes:

• Support for Macintosh Object Pascal in Macpas mode (includes support for mixing in Delphi-style OOP programming in Macpas mode, except that you have to use 'object' instead of 'class' everywhere -- all occurrences of 'class' are simply internally replaced by the _OBJECT compiler token)
• Fixed bug which caused stack corruption in procedures receiving floating point parameters and parameters on the stack (only if the caller side was compiled by FPC)
• Fixed bug in overflow checking of integer operations (some calculations were buggy if overflow checking is turned on, which is the case in the default development building style of Xcode if you use the integration kit)
• Fixed bug in division of unsigned numbers > $7fffffff by a power of 2

Should you desire to do so, you can switch back to 2.0 by simplyinstalling the 2.0 package again.
2005-05-15:
At last !!!!! Free Pascal 2.0 is released for Mac OS X and classic Mac OS,as well as for other targets.
This means Free Pascal for the mac is not considered beta anymore.Get it on one of the mirror download sites.

Targets on the Macintosh:

Target / Processor	Status	Remark	Contact
final	For Mac OS X
final	Target Mac OS means classic Mac OS, up to System 9.x. Although it of course also work in the classic environment in Mac OS X
Mac OS on M68K	not planned	If someone is interrested to contribute, there is a possiblity to implement this target. There is support for MC68000 in the FPC source code, although not updated for a while.

Mac Pascal dialect

The dialect of Pascal supported by popular Pascals on Macintosh is supported in part. Read more here.

Free Pascal 2.0 for Mac OS X is the current release. It should at least work on Mac OS X 10.1 and higher. It requires that you have installed XCode from Apple, to have assembler, linker and make tools available to fpc. For older versions of Mac OS X you should install Apple Development Tools instead. Both can be downloaded for free from Apple, but requires that you register yourself as a member of Apple Developer Connection. Both are also included in the Mac OS X bundle.

To download, go to the Download page, and choose a mirror site near you (to limit net traffic). The documentation is included, but can also be downloaded separatelly. If you want the source code, it has to be downloaded separatelly.

There most recent FPC 2.1.1 snapshot is available here (10.4 MB)with, among others, support for mac style object pascal. See above under NEWS.

Note that the compiler is a unix style program and is run from the Terminal on Mac OS X.

Mac Os Compiler

Please report any bugs encountered.

Using FPC from XCode

It is possible to use Free Pascal from within XCode (Mac OS X 10.3 is required).Look at the step-by-step instruction of how to download and install the XCode Integration Kit. Thanks to Rolf Jansen for this contribution.

Free Pascal 2.0 for Mac OS is the current release. It will work on latest classic Mac OS (that is 9.2.2) and below, probably down to 7.1.2 (the first Mac OS for PowerPC), and also in the classic compatibility environment on Mac OS X. However it has only been tested on Mac OS 9 and Mac OS X classic environment.

It requires that you have installed Macinstosh Programmers Workshop (MPW) which can be downloaded for free from Apple.

To download, go to the Download page, and choose a mirror site near you (to limit net traffic). The documentation, as well as the source code (if you need it), has to be downloaded separatelly.

Note that the compiler is an MPW tool.

Please report any bugs encountered.

Current status of classic Mac OS

Native FPC compiler (as an MPW tool)	Almost complete
Unit System.pp	Complete	The system unit is implicitly used by every program. Contains basic file and memory handling among others.
Unit Dos.pp	Complete	Contrary to what its name suggests, the DOS unit is cross plattfrom and contains utility routines for file and date handling, beyond that in System.pp. It is reminiscent from Turbo Pascal.
Unit Sysutils.pp	Planned	A moderner alternative to unit DOS, compatible with Delphi.
Unit MacOS	Complete	API to the Macintosh Toolbox
Units strings objpas heaptrc getopts etc	Implemented.	They are target independent.
Other units	Non-existent. Some will be implemented.	Implementation will depend on how important the unit is and if difficulties arise.

Debugging

There is some limited possibilities to debug programs in classic Mac OS. See MPW debugging in the wiki.

As an alternative, you might do the main debugging in a Mac OS X/Darwin version of your program.

There are three major Pascal dialects: Turbo Pascal (extended to Delphi, supported by FreePascal, and partially by Gnu Pascal), Extended Pascal (an ISO standard, supported by Gnu Pascal, DEC Pascal, Prospero Pascal), and the dialect originating from Apple (commonly used in the Mac community, supported by MPW Pascal, Metrowerks Pascal and Think Pascal). We call this dialect Mac Pascal and there is a special language mode for it: MacPas.

Free C Compiler For Mac Os X

Mode MacPas is a compatibility mode. It is probably not possible to mimic the Mac Pascal dialect in detail. So the goal is to implement often used constructs, if this doesn't require too much effort, as well as easy-to-implement constructs.

To use MacPas, add -Mmacpas to the command line or insert the compiler directive {$MODE MACPAS} in the source code.

Note that the mac pascal dialect and mac targets are not interrelated. It is thus possible to write a mac program with the turbo dialect and to write a Windows program with the mac dialect.

Free C Compiler For Mac Os X

The following are supported: Mac compiler directives like $SETC, $IFC, $ELSEC, $ENDC, $J, $Z. Most of the constructs found in interface files, especially Apples Universal Interfaces. Cycle, Leave, Otherwise. More is planned.

More updated info on the Wiki page.
