Accessing string with percentage symbol strips it

[igorkulman]

I am using SwiftGen to generate strings with the structured swift5 template

strings:
  inputs:
    - Source/Localization/en.lproj/Localizable.strings
    - Source/Localization/en.lproj/Localizable.stringsdict
  outputs:
    params:
      publicAccess: true
      enumName: LocalizedString
    templateName: structured-swift5
    output: Source/LocalizedString.swift

If I have a string that contains the percentage symbol, like

"percentage_symbol_test" = "Result is 100%";

accessing LocalizedString.percentageSymbolTest gives me Result is 100 with the percentage being stripped.

I'm seeing this issue as well.

I've found a workaround however, which i'm using whenever I need to use the % symbol in my strings. I simple substitute the symbol with a %@ placeholder, which allows me to input the % symbol as a string in code.
I will give an example using the above code:
"percentage_symbol_workaround" = "Result is %@";

and the usage in Swift code:
L10n.percentageSymbolWorkaround("100%");

My workaround us doubling the percentage symbol, so "percentage_symbol_test" = "Result is 100%%";

Duplicate of quite a few issues:

• String with % (100% for example) String with % (100% for example) #831
• Strings: % formatting Strings: % formatting #577
• Problems with '%' symbol Problems with '%' symbol #460

This is an effect of all translations being run through String(format:). At some point we tried being "smarter" about this, i.e. detect if there were any parameters in the translation, and if not, to not run it through String(format:), but that led to a whole bunch of bugs for other users, so we quickly had to revert it.

TL;DR: you have to escape the %, so your string becomes: Result is 100%%.

Thanks @djbe for the info! It makes sense now that you've explained the String(format:) side effects. Perhaps it would be worth updating the README with this info as "gotcha" or something?

I guess I could have found this out by searching the closed issues but I don't normally go to that much effort before raising an issue tbh 😅 .
