Ich versuche, das Flaggenbild von dieser API zu erhalten http://restcountries.eu/rest/v2/all

Es liegt kein Fehler vor, aber das Bild wird nicht angezeigt. Aber es gibt kein Ergebnis, wenn jemand hier dieses Problem beheben kann.
Bitte nicht, dass alles in Ordnung ist und versuchen Sie nicht, das Bild auf zu viele Arten zu erhalten, aber immer noch kein Ergebnis.

Außerdem versuche ich das

[code] let urlString = "http[enter image description
here][1]://restcountries.eu" + (countrie?.flag)!
