问题
I just submitted an app update to the iOS AppStore with 64-bit and 32-bit compatibility. I haven't changed anything except the 64-bit architecture, however the app size is now almost doubled from a pre-64-bit size of 2.7 MB to 4.5 MB.
Is this normal when compiling the app for both 64-bit and 32-bit iOS devices? Why does this happen (anyone care to explain in technical terms)? Or did something funky just happen in Xcode?
回答1:
It's pretty normal because the code is compiled twice - once for 32 and once for 64-bit architectures.
