Develop iOS app for 64bit

Question

After creating project or workspace in xcode do I need to explicitly set the app for 64bit environment in anywhere in project settings?

Thanks in advance for the help.

Answer 1

iOS 11 doesn't support 32-bit. By default Xcode sets 64-bit.

In Xcode 8 and below, make sure you add arm64 to Valid Architectures and select Standard Architectures .

Answer 2

XCode中新创建的项目将自动支持当前（64位）体系结构。
