Swift错误＆＃34;容器文字中的预期表达式＆＃34;变量声明

Question

消息＆＃34;容器文字中的预期表达式＆＃34;继续出现在变量行中。代码如下：

import ResearchKit

public var ConsentDocument: ORKConsentDocument {

let consentDocument = ORKConsentDocument()
consentDocument.title = "Example Consent"

let _: [ORKConsentSectionType] = [
var consentSection: [ORKConsentSection] = consentSectionTypes.map { contentSectionType in
let consentSection = ORKConsentSection(type: contentSectionType)
consentSection.summary = "x."
consentSection.content = "y."
return consentSection
}

很抱歉这个混乱。
