How to force Delphi 10.2.1 to generate 64 bit code for IOS app

Question

I am using Delphi 10.2.1 to write an IOS app but I cant get Delphi to generate 64 bit code. When I run the app in the IOS simulator I get a message telling me the code needs to be updated. Is there a compiler directive I can use to force 64 bit code generation?. I am coding on a 64 bit windows system using a x64 based processor. On the Mac: Xcode is Ver 8.3.3.

Answer 1

Currently Delphi only supports 32-bit compiler for the iOS simulator. There is nothing you can do here. You can only generate 64-bit code for the real devices.

Delphi iOS Compilers - 10.2 Tokyo:

• DCCIOSARM, the Delphi Compiler for the 32-bit iOS Device
• DCCIOSARM64, the Delphi Compiler for the 64-bit iOS Device
• DCCIOS32, the Delphi Compiler for the iOS Simulator

Answer 2

Delphi 10.3 will support 64bit compilers on MACOS this means that only with the next release of delphi it will be possibile to compile also (probably) on 64bit iOSSimulator that is based on the Mac Compiler for Intel 64.
