It is weird to have breaking changing in the bahaviour of the Foundation library APIs depending on the target platform. Before iOS 17 the URL(string:) initializer failed when the string argument was not a valid URL.<\/p>\n\n\n\n

    let url = URL(string: \"invalid url\")
    \/\/ in iOS >=17 this is a valid URL object with value invalid%20url
    \/\/ in iOS <17, MACOS 13.6, Linux this is nil
<\/code><\/pre>\n\n\n\n\n\n\n\n
In the documentation<\/a> it seems that for apps linked on or after iOS 17 and aligned OS versions, URL<\/code><\/a> parsing has updated from the obsolete RFC 1738\/1808<\/em><\/p>\n\n\n\n

I found out this by accident from a failing unit test, that checked the expected behaviour when the a stirng is not valid URL.<\/p>\n\n\n\n
To get the old behaviour you will need to use the URL(string:encodingInvalidCharacters:) initialiazer, that is ofcourse available only in iOS >=17. <\/p>\n\n\n\n
