Hi there, is there a way to change the strings language that is being served in iOS?
I have tried doing that by changing the StringDesc.LocaleType by it does not work (or I am missing something).

fun setLocale(locale: String) {
  StringDesc.localeType = StringDesc.LocaleType.Custom (locale)
}

hi.
StringDesc locale change language only for StringDesc.localize results. if you read string not by StringDesc.localize you will read system language

Also, what is the exact locale you are passing and do you have this exact resource directory?

You have to pass the exact locale as the resource directory is named under resources/MR/*.
So if you have a directory called fr, you cannot pass fr-FR as a locale. You must pass fr, or add some additional logic to resolve this

for apple we search dir with name <locale>.jproj - https://github.com/icerockdev/moko-resources/blob/df157ee999b787bf0d3628ab33747ce5[…]/appleMain/kotlin/dev/icerock/moko/resources/desc/StringDesc.kt
for android we use system logic with Context locale change - https://github.com/icerockdev/moko-resources/blob/df157ee999b787bf0d3628ab33747ce5[…]src/androidMain/kotlin/dev/icerock/moko/resources/desc/Utils.kt
for jvm we pass locale to class loader api - https://github.com/icerockdev/moko-resources/blob/df157ee999b787bf0d3628ab33747ce5[…]src/jvmMain/kotlin/dev/icerock/moko/resources/StringResource.kt
for js we search localization file with <locale> name - https://github.com/icerockdev/moko-resources/blob/df157ee999b787bf0d3628ab33747ce5[…]/kotlin/dev/icerock/moko/resources/provider/JsStringProvider.kt

Hi there, I have fresh news.

1. I wanted to have greek language as my base, so in the base folder strings.xml file I had greek strings.
2. I have also created a second folder named “en” for the english strings.
3. Finally I tried setting iosBaseLocalizationRegion = "el" (not worked) and leave it blank (also not worked)
The setup that seems to work (I must confirm it 100%) is this:

1. The base folder contains the english strings
2. I have also created a second folder named “el” for the greek strings.
3. iosBaseLocalizationRegion = "en"
4. In order to change locale I call the function:

fun setLocale(locale: String) {
    StringDesc.localeType = StringDesc.LocaleType.Custom (locale)
}

with the appropriate locale (“en” or “el”).

[ptsiogas]

The locale change seems to work fine. The final issue that I have to figure out is that the english strings appear with their keys (e.g home_screen_title) and not with their values.
The produced Localizable.strings file seems fine but I suspect that there is a typo somewhere in the strings.xml file.

[alex009]

correct is use base for greek and setup valid base localization.
maybe you not setup xcode project? https://github.com/icerockdev/moko-resources#installation
check ios-app Info.plist block

[alex009]

if you see keys on ios instead of locales - maybe you have static framework and need to setup additional build phase https://github.com/icerockdev/moko-resources#static-kotlin-frameworks-support

[ptsiogas]

The setup seems ok. I see keys because the exported Localizable.strings file for english was invalid and the iOS did a fallback and returned the key.
In order to confirm that the content of the Localizable.strings was invalid I took it’s strings and placed them into xcode’s Localizable strings. Then I took a compile error.

This time the issue was the text above:

"my_key" = "Click \\"Continue\\" to choose how you want to receive the new equipment.\\"";

and the KMM string was this:

<string name="my_key">Click \&quot;Continue\&quot; to choose how you want to receive the new equipment.\&quot;</string>

Apparently there was no compile issue and the android code worked fine. If I may suggest, there should be an extra check in order to determine that the produced Localizable.strings file inside any .lproj folder is valid.

[alex009]

maybe you know some cli cmd for check correctness of this file?

[ptsiogas]

@alex009 about the base folder you are right, there was no need to change it.

[ptsiogas]

I have tried the command tool below but I have not seen it in depth:

plutil -lint Localizable.strings

[ptsiogas]

In the example that I described above it worked fine

Hi there, I also tried to change locale from app.
if I set localeType in start up it is working
import SwiftUI
import shared

@main
struct iOSApp: App {
init() {
//here
KoinHelperKt.doInitKoin()
}

var body: some Scene {
WindowGroup {
ContentView()
.preferredColorScheme(.light)
}
}
}
but later when I tried to call it in runtime, it did not work
fun setLocale(locale: String) {
StringDesc.localeType = StringDesc.LocaleType.Custom(locale)
preferenceManager?.setLocale(locale)
}

I'm new to iOS development, need some instructions. Thanks in advance!

[alex009]

You should trigger reloading of you UI, it can't be triggered automatically from kotlin

@alex009 thanks a lot it worked. 👍
