Build, size, and compatibility

Common SDK build and compatibility topics.

App Store submission: strip simulator architectures

SDK .framework binaries may include simulator architectures (x86_64). Strip them before App Store submission. The SDK provides prepare-framework-to-publish-to-appstore.sh:

bash libs/prepare-framework-to-publish-to-appstore.sh

NOTE

With .xcframework, stripping is not required; platform slices are already separated.

Bitcode support

From Xcode 14 onward, Apple removed Bitcode support. On older Xcode versions, if you see Bitcode link errors, set Enable Bitcode to No in Build Settings.

Mac Catalyst support

To build an iPad app for Mac (Mac Catalyst):

1. Use .xcframework library variants.
2. In Target → General → Deployment Info, enable Mac (Designed for iPad).
3. Requires macOS 10.15+ and Xcode 11+.

Minimum deployment target

SDK version	Minimum iOS
9.x	iOS 11.0
7.5.1+	iOS 11.0 (64-bit only)

Package size optimization

• If you do not need all UI Extensions features, load modules selectively with UIExtensionsConfig.
• Do not link FoxitPDFScanUI.framework if scanning is not required.
• .xcframework with App Thinning can reduce installed app size.
