Hi @dev thanks for reporting the issue, I think this issue is not in my knowledge I had tested the code and many applications used it, although I couldn't help today but surely look into this Asap. Please share the details so that I can help you smoothly.

Solution

    func fetchSectionCountries() {
        sections = countries.map({ String($0.countryName.prefix(1)).first! }).unique

        for section in sections {
            let sectionCountries = countries.filter({ (country) -> Bool in
                return country.countryName.first! == section
            })
            sectionCoutries[section] = sectionCountries
        }
    }

extension Array where Element : Equatable {
    var unique: [Element] {
        var uniqueValues: [Element] = []
        forEach { item in
            if !uniqueValues.contains(item) {
                uniqueValues += [item]
            }
        }
        return uniqueValues
    }
}

Nice to know you had solve the problem 🥇 could you please explain a bit how it solve the problem? So that i update my repo accordingly. it is seems like is Duplicacy is the problem (Not clear for me how) ? is it please let me know.

You get country names from the system, and it depends on device language.

for non English languages, constant "sections" with English letters will be wrong, so I just initiated sections with first letter from each language name,

countries.map({ String($0.countryName.prefix(1)).first! })
then filtered the duplicates.

.unique
Best
