将react-native包从0.63.4升级到0.64.4后,在模拟器和设备上构建和运行应用程序时,我在Xcode(在MacBook Pro M1上)中遇到以下错误:
我尝试过使用或不使用脚蹼,但没有任何帮助。还手动将 CoreFoundation 和 Foundation Framework 添加到项目中,并在启用和不启用 Rosetta 的情况下运行 Xcode。

这是我的代码:
filterDatasource(event)
{
var searchString = event.nativeEvent.text.toLowerCase();
if (searchString != "")
{
var content = this.state.loadedContent;
var searchResultsArray = [];
for (var i = 0; i < content.length; i++) {
var detailArray = content[i];
const gattung = detailArray.Gattung;
const zugnummer = detailArray.Zugummer;
const ab = detailArray.ab;
const bis = detailArray.bis;
const wochentag = detailArray.Wochentag;
const zeitraum = detailArray.Zeitraum;
