Embarcadero has released a patch that adds support for building and debugging iOS 11 applications on supported devices, and building App Store, Ad Hoc or In-House Distribution ready apps. It also addresses a number of iOS 10 related issues.
This patch is available for any active Update Subscription customer and requires that you have RAD Studio 10.2.1 (Tokyo Release 1) installed.
Supported iOS SDK versions: iOS 10.3.x, iOS 11
Supported Xcode versions: Xcode 8.2.x, 8.3.2, 8.3.3 and 9.0
Note: iOS 11 Simulator deployment is currently not supported as it requires macOS 64-bit support. macOS 64-bit support is on our product roadmap. Targeting iOS 10 Simulator devices is supported.
