Research direction

Start by reproducing the issue with @capacitor/share on iOS using the provided vCard generation and file-sharing code, then inspect the plugin's iOS implementation for file attachment handling. Done means the generated .vcf can be shared successfully through Gmail and Slack, with regression coverage for this case if the plugin has relevant tests.

Expected Behavior

Possible to share vcard file by Gmail and Slack

Code Reproduction
    if (!text) return '';

    return text
      .replace(/\\/g, '\\\\')
      .replace(/\n/g, '\\n')
      .replace(/,/g, '\\,')
      .replace(/;/g, '\\;');
  }
  toAsciiFileName(s: string) {
    return (s || '')
      .normalize('NFD')                 
      .replace(/[\u0300-\u036f]/g, '') 
      .replace(/[^a-zA-Z0-9_-]/g, '_');
  }

  generateVCard(contact: {
    firstName: string;
    lastName: string;
    phone?: string;
    email?: string;
    organization?: string;
    address?: string;

    lines.push('VERSION:3.0');
    const lastName = this.escapeVCard(contact.lastName);
    const firstName = this.escapeVCard(contact.firstName);
    lines.push(`N:${lastName};${firstName};;;`);
    lines.push(`FN:${firstName} ${lastName}`.trim());

      const escapedParts = addressParts.map(part => this.escapeVCard(part));
      lines.push(`ADR;TYPE=HOME:;;${escapedParts.join(';')}`);
    }
    if (contact.website) {
      lines.push(`URL:${this.escapeVCard(contact.website)}`);
    }
    lines.push('END:VCARD');

    const dir = Directory.Documents;
    await Filesystem.writeFile({path: fileName, data: this.vcardValue, directory: dir, encoding: Encoding.UTF8});

    const {uri} = await Filesystem.getUri({directory: dir, path: fileName});

    await Share.share({
      title: `${this.firstname} ${this.lastname}`.trim(),
      dialogTitle: 'Share contact',
