Generate Object Pascal Headers Of IOS And OSX Frameworks For Firemonkey In #Delphi 10 Berlin

Delphi 10 Berlin includes a new tool called SdkTransform which generates Object Pascal header files for IOS and OSX frameworks. The tool is command line based. HOSOKAWA Jun, a Delphi developer out of Japan, has created a Windows GUI front end in Firemonkey for SdkTransform which makes it as simple as selecting where you want to output the Objective-C Bridge files and then clicking one button to generate them all. The source code for the SDK Transform Assistant app is available on Github. I downloaded the source and compiled it under Delphi 10 Berlin. If you installed Delphi Berlin from ISO it should automatically detect the location of CLang. If you installed using the new GetIt installer you will have to set the CLang path manually. On my machine Windows 8.1 the CLang path ended up being “C:\Users\Public\Documents\Embarcadero\Studio\18.0\CatalogRepository\AndroidNDK-9c_x86_GIB.Build.22858.6822\toolchains\llvm-3.3\prebuilt\windows\lib\clang\3.3\include”. Once the paths are setup correctly and you set an output path just click start and it will generate all of the Object Pascal files. One thing to note is that you have to add the IOS and OSX frameworks that you want generated to the Delphi SDK Manager prior to generating the bridge files. Otherwise you will just get the default frameworks. Here is an excerpt created for the IOS Security framework:

const
libSecurity = ‘/System/Library/Frameworks/Security.framework/Security’;
function CF_ENUM(param1: SSLCipherSuite): Integer; cdecl;
external libSecurity name _PU + ‘CF_ENUM’;
function SecAccessControlGetTypeID: CFTypeID; cdecl;
external libSecurity name _PU + ‘SecAccessControlGetTypeID’;
function SecAccessControlCreateWithFlags(allocator: CFAllocatorRef;
protection: CFTypeRef; flags: SecAccessControlCreateFlags; error: Pointer)
: SecAccessControlRef; cdecl;
external libSecurity name _PU + ‘SecAccessControlCreateWithFlags’;

There is also an SDKTransformTypes.txt file in the Delphi Berlin bin directory which shows how SDKTransform will map the types from Objective-C to Object Pascal. Here is the complete types map list:

HOSOKAWA Jun has a more extensive blog post (in Japanese) about SDKTransform, the CLang directory structure, and SDK Transform Assistant in a blog post. You can use the translate function in Chrome if needed. If you need to translate Java headers for Android try Java2OP.
