In my application, I have some code to fetch the range of the host in a URL
. It looks like this:
private func rangeOfHost(text: String) -> NSRange? {
let url = URL(string: text)
if let host: String = url?.host {
if let range = text.range(of: host) {
return NSRange(
location: range.lowerBound.encodedOffset,
length: range.upperBound.encodedOffset - range.lowerBound.encodedOffset
)
}
}
return nil
}
Xcode has been warning me that 'encodedOffset' is deprecated: encodedOffset has been deprecated as the most common usage is incorrect. Use utf16Offset(in:) to achieve the same behavior.
. However, it's not clear to me how I can replace those encodedOffsets with these suggestions. Any ideas?
A simple and correct way to create an NSRange
from a Range<String.Index>
is to use its initializer:
public init<R, S>(_ region: R, in target: S) where R : RangeExpression, S : StringProtocol, R.Bound == String.Index
In your case:
if let range = text.range(of: host) {
return NSRange(range, in: text)
}
yourString1.yourIndex.utf16Offset(in: yourString2)
