What is an App? An application, or app for short, is a software application made to carry out particular functions on computers, tablets, and smartphone platforms. Apps can be used for a variety of things, such as productivity and utility, social networking, and entertainment. Usually, people may download and install them with ease via app stores like Google Play or Apple's App Store. Applications can be web-based and accessed via web browsers, or native, designed for a particular operating system. By providing specialised features, they improve the functionality of gadgets and frequently increase efficiency and user experience. The increasing use of mobile technology has made applications essential to both daily life and commercial operations. What are Some Different Types of Apps? Apps are available in many different formats, each with a distinct purpose and user requirement in mind. They might be as basic as productivity-boosting gadgets or as sophisticated as social media platforms or entertainment servic

You should probably place this post in the UIKit topic instead so it's less confusing. ‎ In UIKit above property isn't available I believe UIDatePicker has a locale property that you can assign a custom locale to. It will do the same as the SwiftUI solution. If this doesn't work, or you have already tried it, then you need to provide more context and the code you are using so we can understand what is going on. 0 comments [/quote] yes, but if i set custom locale us_POSIX locale for 12 hour and us_GB for 24 hour format. working fine in device use gregorian calendar else datePicker year not showing properly in month & year section like when i use japanese calendar year shows 6 instead of Reiwa 6

How are you setting your locale? If you aren't already, you can set it through the environment, like this: DatePicker(...) .environment(.locale, myCustomLocale) You can customise a Locale object with the values you want for specified properties, such as the region or calendar.

The format strings are designed for the Gregorian calendar. If this is meant to be shown to the user, you should an appropriate localized format.

Did you find a solution for this? I have a user experiencing the same on iOS 17.5, on any calendar.

My issue was successfully resolved by the Apple's engineering team. Whole process took about 6-7 calendar weeks and I believe making this forum thread speed it up.

Just to follow up on this a bit, I did find that Apple apparently changed semantics since the WWDC video was made, and they introduced a DonationTimeRange structure that you can use like this: #Rule(Self.viewedDetails) { $0.donations .donatedWithin(.days(5)) .count > 0 Unfortunately, this doesn't provide a way to achieve what I want for one of my rules, which is to determine if the user has been using the app for at least a calendar day. You might think that you could construct an expression comparing the count of two .donatedWithin ranges: #Rule(Self.viewedDetails) { $0.donations.donatedWithin(.weeks(52)).count > $0.donations.donatedWithin(.days(1)).count But no, you can't. This doesn't work because the #Rule macro explicitly requires a count comparison. If you try to write it as a raw predicate expression, it will compile but assert at runtime. So, at this point, I've given up trying to write the rule that I wanted to write. But perhaps someone will see the question and point out something th

Consider this: import Foundation func main() { var c = Calendar(identifier: .gregorian) c.timeZone = .gmt let jan2022 = c.date(from: .init(year: 2022, month: 1, day: 1))! let jun2022 = c.date(from: .init(year: 2022, month: 6, day: 1))! let jan2023 = c.date(from: .init(year: 2023, month: 1, day: 1))! let jun2023 = c.date(from: .init(year: 2023, month: 6, day: 1))! let tz = TimeZone(identifier: America/Merida)! for d in [jan2022, jun2022, jan2023, jun2023] { print(tz.isDaylightSavingTime(for: d), tz.daylightSavingTimeOffset(for: d), tz.secondsFromGMT(for: d) / 60 / 60) } } main() On macOS 14.4.1 it prints: false 0.0 -6 true 3600.0 -5 false 0.0 -6 false 0.0 -6 That definitely matches your assertion that this time zone is ‘stuck’ on standard time rather than daylight savings time. However, I’m confused by this assertion: Essentially America/Merida permanently changed to -0500 (CDT) on October 31, 2021 The Wikipedia summary of Mexican time zones suggests that America/Merida is effectively deprecated in fa
