I want to translate this string using a plurar stringdict in swift for iOS
Using a simple plural without placeholders works, thanks to this question But when I add a string placeholder I get a crash when accessing it.
The regular plurals are working using the following xml:
<dict>
<key>NSStringLocalizedFormatKey</key>
<string>%#@format@</string>
<key>format</key>
<dict>
<key>NSStringFormatSpecTypeKey</key>
<string>NSStringPluralRuleType</string>
<key>NSStringFormatValueTypeKey</key>
<string>li</string>
<key>one</key>
<string>Sleeps at your place</string>
<key>other</key>
<string>Sleep at your place</string>
</dict>
</dict>
And using this swift code to reference the plural above without string placeholder:
let format = NSLocalizedString("key_to_plural_above", comment: "")
let label = String.localizedStringWithFormat(format, kidsIds.count)
The problem is when I add a string placeholder to the translation I get a crash when I try to read it. The xml below is generated by a translation tool (lokalise) so I assume it's correct.
<dict>
<key>NSStringLocalizedFormatKey</key>
<string>%#@format@</string>
<key>format</key>
<dict>
<key>NSStringFormatSpecTypeKey</key>
<string>NSStringPluralRuleType</string>
<key>NSStringFormatValueTypeKey</key>
<string>li</string>
<key>one</key>
<string>Sleeps at %1$@</string>
<key>other</key>
<string>Sleep at %1$@</string>
</dict>
Using this swift code to get the plural above, I get an unknown crash without any stacktrace:
let format = NSLocalizedString("key_to_plural_above", comment: "")
let label = String.localizedStringWithFormat(format, kidsIds.count, "Name")
Positional parameters n$
are one-based, so in
let label = String.localizedStringWithFormat(format, kidsIds.count, "Name")
"Name"
is the second parameter, and you reference it with %2$@
:
<key>NSStringLocalizedFormatKey</key>
<string>%#@format@</string>
<key>format</key>
<dict>
<key>NSStringFormatSpecTypeKey</key>
<string>NSStringPluralRuleType</string>
<key>NSStringFormatValueTypeKey</key>
<string>li</string>
<key>one</key>
<string>Sleeps at %2$@</string>
<key>other</key>
<string>Sleep at %2$@</string>
</dict>
In your code, %1$@
refers to the first argument kidsIds.count
.
That is not a string which leads to the crash.
Alternatively, put it into the NSStringLocalizedFormatKey:
<key>NSStringLocalizedFormatKey</key>
<string>%#@format@ at %@</string>
<key>format</key>
<dict>
<key>NSStringFormatSpecTypeKey</key>
<string>NSStringPluralRuleType</string>
<key>NSStringFormatValueTypeKey</key>
<string>li</string>
<key>one</key>
<string>Sleeps</string>
<key>other</key>
<string>Sleep</string>
</dict>
