When I install app over OTA, it says "my app May Slow Down your iPad - The developer of this app needs to update it to improve its compatibility". I researched and I got that my application is running with Architectures 32 bit $(ARCHS_STANDARD_32_BIT), it need to convert to 64 bit.
I changed Architectures to Standard architectures (armv7, arm64). Valid Architectures: arm64 armv7 armv7s. Build Active Architecture to NO:
Then My app can work in simulator but When I Archive Xcode say that "Build Fail"
How can I do that?
Hard to say without seeing any error message, but you have obviously not updated your app in ages (since 32-bit only hasn't been allowed for years), so I suspect that you may be using some 32-bit only libraries that you need to update.
